   Thank you very much to everyone who is trying to help me by answering my question here. 
   On this occasion I would also like to thank to @acassis for his kindly answering my questions in LinkedIn messaging.
   
   @anchao I just applied exactly same process [here in @acassis 's blog "Using NuttX as library once again" ]( https://acassis.wordpress.com/2020/06/28/using-nuttx-as-library-once-again/ )
   
   Everything went as expected until I enter this command:
   `$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/ld.script -L./libs hello.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx "/usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a" --end-group`
   
   then I got the following:
   `.apple-MacBook-Pro:hello murat$ cd nuttx-export-9.0.0
   apple-MacBook-Pro:nuttx-export-9.0.0 murat$ arm-none-eabi-gcc -c -fno-builtin -Wall -Wstrict-prototypes -Wshadow -Wundef -g -mcpu=cortex-m4 -mthumb -mfloat-abi=soft -I. -isystem ./include   -pipe -I "./include" -I "./arch/chip" hello.c -o  hello.o
   apple-MacBook-Pro:nuttx-export-9.0.0 murat$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/ld.script -L./libs hello.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx "/usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a" --end-group
   arm-none-eabi-ld: cannot find -lc
   arm-none-eabi-ld: cannot find -larch
   arm-none-eabi-ld: cannot find -lbinfmt
   arm-none-eabi-ld: cannot find -lboard
   arm-none-eabi-ld: cannot find -lboards
   arm-none-eabi-ld: cannot find -ldrivers
   arm-none-eabi-ld: cannot find -lfs
   arm-none-eabi-ld: cannot find -lmm
   arm-none-eabi-ld: cannot find -lsched
   arm-none-eabi-ld: cannot find -lxx
   arm-none-eabi-ld: cannot find /usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a: No such file or directory
   `
   Note: with Nuttx version 9.1.0 the first command line (arm-none-eabi-gcc -c ... ) didn't work either.
